The project is Staples’ 37th solar array and the latest example of Staples’ long-standing commitment to environmental sustainability. The installation brings the company’s use of solar power to a total of nearly 14 megawatts across its operations nationally, which is equivalent to powering nearly 1,800 average US homes for one year. Staples is ranked among the top ten renewable power users on the Environmental Protection Agency’s Green Power Partnership list.

The 685 kilowatt solar installation in Framingham consists of more than 2,440 SunEdison Silvantis™ solar modules and will generate an estimated 850,000 kilowatt hours (kWh) of energy annually to help power Staples’ 650,000 square-foot headquarters office building. The solar power system will offset more than 12,000 tons of carbon dioxide (CO2) over the next 20 years—a reduction equivalent to removing more than 2,300 cars driving 12,000 miles per year. Staples’ total solar power use nationally has offset more than 42,000 tons of CO2 over the past eight years.

“This solar power system at our global headquarters is a demonstration of Staples’ dedication to sustainability across our business,” said Mark Buckley, vice president of environmental affairs for Staples. “Our partnership for solar energy with SunEdison provides cost-effective power and helps Staples meet its environmental goals.”

The SunEdison/Staples solar program is made possible through power purchase agreements between SunEdison and Staples which require no capital outlays from Staples. SunEdison develops, finances, and operates and manages the solar installations, and Staples buys the energy produced at long-term, predictable pricing.

“Staples has been a long-standing partner of SunEdison. We applaud the management team for their strong commitment to environmental sustainability,” said Attila Toth, general manager distributed generation for SunEdison. “Through our advanced technologies, proven asset management and financing capabilities, SunEdison is able to deliver competitively priced solar energy to clients like Staples worldwide.”

Staples has used more than 48 million kWh of solar energy since 2005 from 37 solar arrays. Staples uses renewable power for 100 percent of its total US electricity consumption – which is more than 636 million kWh – through on-site solar projects combined with green power purchases. That’s the equivalent of powering more than 67,000 average US homes for a year. The power from these renewable sources is used across the company’s facilities, including Staples retail stores, delivery fulfillment centers, customer service call centers and sales offices.
